Frog’s Life Cycle
Why we need them?1.Frogs and toads are a part of the planet’s bio-diversity.
2.Amphibians are highly sensitive to changes in the environment and are aptly considered as "CANARIES IN A COAL MINE”.
3.Major biological controller of insects,some of which can cause disease to humans, transmitters of disease or pest of agriculture.
4.Tadpoles scrapes and feed on algae (green,brown,red algae,diatoms),zooplankton and larvae of some insects in the water bodies, thus controlling algal blooms to certain extent.
5.Frogs and toads are also the food for other species like birds,snakes,small mammals etc.
6.The skin of frogs and toads are store house of novel chemical compounds which are useful in developing new drugs to cure many diseases from HIV to ulcer.
7.Frogs and toads were part of culture since the beginning of civilization

TERRESTRIAL AND BURROWING
THREATS
Rapid urbanization, Changes and degradation of habitats(Conversion of forest ,dam construction etc..),
Climate change ,
Usage chemical pesticides and fertilizers,
invasive species and infectious diseases are few prominent reasons for global amphibian decline.
Food.
During the rainy season they become victim of their greatest
predator – HUMAN BEING.
Human beings are most responsible for killing Frogs & invite various
diseases like Encephalities, Dengue, Malaria, Filaria etc.
SAY NO TO FROG MEAT
And don’t forget to spread this
message among the all people.
Beware!
FROGS are Protected Under Schedule
IV of the Wildlife (Protection) Act, 1972.Catching, killing and selling frogs or serving
Frog meat in eating places contravene the
provisions of the Act, and attracts stringent
punishment with fine up to Rs. 25,000 and
imprisonment.
